\fBhcitool\fP \-h
.sp
\fBhcitool\fP \fICOMMAND\fP \-\-help
.sp
\fBhcitool\fP [\-i \fIhciX\fP] [\fICOMMAND\fP [\fIPARAMETERS\fP]]
.SH DESCRIPTION
.sp
\fBhcitool(1)\fP is used to configure Bluetooth connections and send some special
command to Bluetooth devices. If no \fBcommand\fP is given, or if the option
\fB\-h\fP is used, \fIhcitool\fP prints some usage information and exits.
.SH OPTIONS
.INDENT 0.0
.TP
.BI \-i \ <hciX>
The command is applied to device \fIhciX\fP, which must be the name of
an installed Bluetooth device. If not specified, the command will
be sent to the first available Bluetooth device.
.TP
.B  \-h
Gives a list of possible commands
.UNINDENT
.SH COMMANDS
.INDENT 0.0
.TP
.B dev

.TP
.B inq
Inquire remote devices. For each discovered device, Bluetooth device
address, clock offset and class are printed.
.TP
.B scan
Inquire remote devices. For each discovered device, device name are printed.
.TP
.B name <\fIbdaddr\fP>
Print device name of remote device with Bluetooth address \fIbdaddr\fP\&.
.TP
.B info <\fIbdaddr\fP>
Print device name, version and supported features of remote device with
Bluetooth address \fIbdaddr\fP\&.
.TP
.B spinq
Start periodic inquiry process. No inquiry results are printed.
.TP
.B epinq
Exit periodic inquiry process.
.TP
.B cmd <\fIogf\fP> <\fIocf\fP> [\fIparameters\fP]
Submit an arbitrary HCI command to local device. \fIogf\fP, \fIocf\fP and
parameters are hexadecimal bytes.
.TP
.B con
Display active baseband connections
.TP
.B cc [\-\-\fIrole\fP=c|p] [\-\-\fIpkt\-type\fP=<\fIptype\fP>] <\fIbdaddr\fP>
Create baseband connection to remote device with Bluetooth address \fIbdaddr\fP\&.
.sp
Option \fB\-\-pkt\-type\fP specifies a list  of  allowed packet types.
<\fIptype\fP> is a comma\-separated list of packet types, where the possible
packet types are \fBDM1\fP, \fBDM3\fP, \fBDM5\fP, \fBDH1\fP, \fBDH3\fP, \fBDH5\fP,
\fBHV1\fP, \fBHV2\fP, \fBHV3\fP\&. Default is to allow all packet types.
.sp
Option  \fB\-\-role\fP can have value \fBc\fP (do not allow role switch, stay
central) or \fBp\fP (allow role switch, become peripheral if the peer asks to
become central). Default is \fBc\fP\&.
.TP
.B dc <\fIbdaddr\fP> [\fIreason\fP]
Delete baseband connection from remote device with Bluetooth address
\fIbdaddr\fP\&.
.sp
The reason can be one of the Bluetooth HCI error codes.
Default is \fB19\fP for user ended connections. The value must be given in
decimal.
.TP
.B sr <\fIbdaddr\fP> <\fIrole\fP>
Switch role for the baseband connection from the remote device to
\fBcentral\fP or \fBperipheral\fP\&.
.TP
.B cpt <\fIbdaddr\fP> <\fIptypes\fP>
Change packet types for baseband connection to device with Bluetooth
address \fIbdaddr\fP\&. \fIptypes\fP is a comma\-separated list of packet types,
where the possible packet types are \fBDM1\fP, \fBDM3\fP, \fBDM5\fP, \fBDH1\fP,
\fBDH3\fP, \fBDH5\fP, \fBHV1\fP, \fBHV2\fP, \fBHV3\fP\&.
.TP
.B rssi <\fIbdaddr\fP>
Display received signal strength information for the connection to the
device with Bluetooth address \fIbdaddr\fP\&.
.TP
.B lq <\fIbdaddr\fP>
Display link quality for the connection to the device with Bluetooth
address \fIbdaddr\fP\&.
.TP
.B tpl <\fIbdaddr\fP> [\fItype\fP]
Display transmit power level for the connection to the device with
Bluetooth address \fIbdaddr\fP\&.
.sp
The \fItype\fP can be \fB0\fP for the current transmit power level (which is
default) or \fB1\fP for the maximum transmit power level.
.TP
.B afh <\fIbdaddr\fP>
Display AFH channel map for the connection to the device with Bluetooth
address \fIbdaddr\fP\&.
.TP
.B lp <\fIbdaddr\fP> [\fIvalue\fP]
With no value, displays link policy settings for the connection to the
device with Bluetooth address \fIbdaddr\fP\&.
.sp
If \fIvalue\fP is given, sets the link policy settings for that connection to
\fIvalue\fP\&. Possible values are \fBRSWITCH\fP, \fBHOLD\fP, \fBSNIFF\fP and \fBPARK\fP\&.
.TP
.B lst <\fIbdaddr\fP> [\fIvalue\fP]
With no value, displays link supervision timeout for the connection to
